Beckett solarH2ot Manual To Selecting And Installing page 18

Two things to note here: head and flow rate of a pump. The head represents how high the pump can
lift a column of water. They measure flow by how much water (gallons or liters) a pump can push at a
given head. A pump head/flow curve for the Armstrong Astro series pumps looks like this.
Ths graph shows that an Astro 70 would push 4 GPM at 23 feet of head.
See the chart below to find which pumps are appropriate for which application. Different manufacturers
pumps can be cross-referenced with this list or the above head/flow graph.
The Beckett SolarHot Advantage: The pumps for both loops come already packaged
into the Solvelox assembly. This gives you confidence that your customer will have the
rght pumps at the tme of nstallaton.
